How do I connect an LED to the GPIO connector (DA15) on the player?

Note:The steps below only recommend wiring the anode to pin 8 for testing. Once that's done, the anode of the LED is wired to a pin like the buttons. BrightSign players support 3.3v LEDs directly, without external power.

Connect the Anode of the LED to pin 8 (PWR), and Cathode to pin 14 (GND). We recommend using a 10-100 ohm series resistor to protect the LED. The LED will be ON and will stay ON because pin 8 is always 3.3V and pin 14 is always GND. Please use this to verify that the LED is working and there is board power.
